Stranger things have happened to things over time. Take for Instance 'SR' somebody smacked or hit/rolled over something in his past life and managed to bend his drive axle. So it would not engage one of the clutches. So what I am trying to say is if you are planning on making a lifer out of it then spend the cast and fix it right. And if you don't than you gotta do what you gotta do to to keep it going for the short term.
